Definitions

  • the present invention relates to water leakage detection devices and more particularly, to a leakage protector apparatus, which is capable of sensing and containing leakage in the water supply line, as well as, leakage occurring from the appliance to which it is connected.
  • Another object of the present invention is to provide a water leakage detecting apparatus capable of sensing leakage from an appliance, when it is operating and turning off the water supply and the electrical power to the appliance.
  • a water leakage protector apparatus for appliances subject to leakage comprises in combination, a first device for detecting water leaking from a water supply line coupled to an appliance and a second device for detecting the water leaking from the appliance.
  • a control apparatus operates valves affixed to said water supply lines, controls the flow of water flowing in the water supply line.
  • the control apparatus is connected to a source of electrical power and the appliance is coupled to the control apparatus to obtain electrical power to operate.
  • a first and a second coupling device couples the control apparatus to the first and the second detecting device. When a water leak is detected by either the first or the second detecting device, the control apparatus stops the water from flowing in the water supply line and interrupts the electrical power to the appliance.
  • FIG. 1 is a pictorial representation of a typical washing machine and its connections to the control apparatus, according to the principles of the present invention
  • FIG. 2 is a greatly enlarged pictorial representation of the control valves coupled to the plumbing system appliance water source
  • FIG. 3 is a functional block diagram showing the operation of the protector apparatus, as shown in FIG. 1.
  • FIG. 1 there is shown a control apparatus 10, which is described in more detail in FIG. 2 . It is seen to include the indicator lights 14, 16, 18 and 20, fuse 22 and reset switch 24. Also included in the control apparatus 10 is an audible alarm or buzzer 26. In addition, the floor liquid sensor 28 is coupled into the control apparatus 10 by a lead wire 30 and a plug 32.
  • the control apparatus 10 is provided with a line plug 12' which is plugged into conventional wall outlet 12 that supplies 110 volts AC at 60 hertz in order to obtain power for operation.
  • a female output receptacle 34 is provided on the control apparatus 10 and is adapted to receive a male plug 36 therein, which is connected by a power cable 38 to the washing appliance 40.
  • the washing appliance 40 is shown as a clothes washer it is to be understood that a dishwasher, etc. may also be used in the same manner and the control apparatus 10 would provide the same type of protection for those appliances also.
  • the hot and cold water supply lines 42 and 44 which include their own manual OFF/ON valves 46 and 48 manually provide the water into the system and generally are left in the ON or open condition once the installation has been completed.
  • Also included in the control valves 54 and 56 are output plugs 58 and 60, which are coupled respectively by cable 62 and 64 and plugs 66 and 68, respectively, to the control apparatus 10.
  • Each of the flexible water supply lines 50 and 52 is a three layered hose having an electrically conductive outer layer, an electrically conductive inner layer and a woven insulating central layer disposed therebetween in a sandwiched manner providing a resistance between the inner and outer layer, which changes when the woven insulating central layer has moisture or liquid appearing within the woven central insulating layer.
  • the resistance may vary from a very large value (open circuit) to a very low value (short circuit) or any value therebetween, depending on the conductivity of the liquid appearing within the woven central layer.
  • the washing machine 40 is provided with a conventional control panel 70, a top opening door 72 and a pump 74 used to discharge the waste water, via an exit hose 75. Should the discharge hose 75 or pump 74 develop a leak, the floor liquid sensor 28 would have a change in resistance between the inner and outer layers similar to that occurring in the input water hose lines 50 or 52.
  • the construction of the floor liquid sensor 28 is identical to that of the hose 50 and 52 except, that it is manufactured as a flat strip.
  • FIG. 2 is a greatly enlarged pictorial representation of the control valves 54 and 56 coupled to the plumbing system appliance water source 42 and 44.
  • the flexible hoses 50 and 52 are fitted with coupling adapters 51 and 53, respectively that couple them to the control valves 54 and 56, respectively while providing electrical separation between the inner and outer layers of the hoses.
  • a change in resistance between the inner and outer layers of the hoses is coupled to the control apparatus 10, via plugs 55 and 57; and jacks 59 and 61, respectively, via cables 62 and 64.
  • FIG. 3 is a functional block diagram describing the operation of the control apparatus 10, as set forth in the instant invention, particularly delineating the important functions.
  • the input power for the operation of the control apparatus 10 is obtained from plug 12' being plugged into the wall receptacle or outlet 12.
  • the input power is provided with a fuse 22 to protect the control circuitry should an unusual amount of current be drawn by the circuit.
  • a power supply circuit arrangement 76 Directly connected to the input power line is a power supply circuit arrangement 76, which is of conventional design and not disclosed herewith in detail.
  • a power control relay 80 Connected in series with the fuse 22 and output receptacle 34, into which the washing machine plug 36 is inserted, are the contacts 78 of a power control relay 80 that has its contacts 78, normally in an open position, until the manual reset switch 24 is activated (closed momentarily) which in turn energize relay 80 closing its contacts, thereby allowing power to be connected to the output receptacle 34.
  • control valves 54 and 56 are coupled to the water input lines 42 and 44 and the manual valves 46 and 48 are opened (turned ON).
  • the control apparatus 10 is plugged into the 110 volt 60 hertz power line 12 and the plug 36 of the appliance (washing machine) 40 is plugged into the output receptacle 34.
  • there are two control valves 54 and 56 it is to be understood that a single control valve can be used if the water input lines are put through "Y" connector so that there is only one output water line, if that is all that is required by the appliance to be operated.
  • the operator of the appliance would then operate the appliance in the normal conventional manner and would be aware of a leakage when it occurs by the sounding of the audible alarm, the condition of the illuminated indicating devices or the turn off of the appliance. Once the leakage has been corrected, the reset button 24 would reset the control apparatus 10 into normal operating condition and the appliance could then be operated in its conventional manner.
  • the indicator lights (illuminating devices) 14, 16, 18, and 20 would perform the following functions:
  • Light 14 illuminated--power is provided to the control apparatus 10;
